Definitions
- the present invention relates to a method and a device for pointing a fixed antenna having a reflector including at least one transceiver source capable of aiming at a plurality of satellites situated between two extreme positions S 1 , S 2 on a geostationary orbit.
- the method and device can also be implemented with an antenna having a source whose radiation pattern is steerable so as to be able to select a selected incident beam from a plurality corresponding to different target orbital positions. It can also be implemented with an antenna provided with a source that is motor-driven along the focal line.
- the antenna can be of the following types:
- an antenna having a reflector in an offset configuration having a focal line comprising as many sources as there are target orbital positions.
- Such antennas are described in document FR 2 746 218, for example, which discloses a support for mounting two converters (transmitter or receiver heads) on a parabolic antenna, and document FR 2 701 337 describes a support for a plurality of receiver heads on a parabolic antenna.
- the invention also applies to an array antenna with azimuth scanning.
- FIGS. 1, 2 , and 3 illustrate a known method of pointing a multi-satellite antenna having a centered-configuration reflector with a plurality of sources on its focal line.
- This pointing consists in aiming at the intermediate orbital position S M where a middle satellite is located, halfway angularly between the extreme positions S 1 and S 2 .
- the antenna is turned about an azimuth axis A and about an elevation axis B as shown in FIG. 4 .
- the antenna is turned about its own axis pointing at the orbital position S M through a roll angle i, and then the spacing between the sources is adjusted so as to receive all of the orbital positions.
- FIGS. 2 and 3 show two intermediate target orbital positions S 3 and S 4 situated between the two extreme orbital positions s 1 and s 2 .
- the idea is to align the transceiver sources s 1 , s 2 , s 3 , s 4 , and s m on the positions S 1 , S 2 , S 3 , S 4 , and S M .
- the object of the invention is to provide a method and a device enabling the above-described drawbacks of the prior art to be mitigated.
- the antenna when the antenna has a plurality of sources, the height of each of them in a plane perpendicular to the plane containing the focal line and the origin O of the focal axis of the reflector is adjusted independently of the others.
- the device for implementing the method of the invention is characterized in that it comprises a mechanism for fixing the antenna to said support, said mechanism also enabling the antenna to be turned through an angle ⁇ about an axis D perpendicular to the plane containing the focal line and the origin O of the focal axis of the reflector so as to steer the reflector transversely.
- FIGS. 1, 2 , 3 , and 4 are diagrams showing the operation of a prior art multi-satellite antenna
- FIG. 5 is a diagram showing how the FIG. 4 antenna is pointed
- FIGS. 6 and 7 are perspective views of an antenna of the invention.
- FIG. 8 is a diagram illustrating how the antenna of FIGS. 6 and 7 is pointed
- FIG. 9 is a diagrammatic plane view of the antenna of FIGS. 6 and 7.
- FIG. 10 is a diagram illustrating how an antenna with a motor-driven single source is pointed.
- an antenna having a reflector in a centered configuration and provided with five transceiver sources is not limited to this type of antenna and the person skilled in the art can easily apply the invention to an antenna having a reflector in an offset configuration or having a focal line that has either a single transceiver source or as many sources as there are target orbital positions, and also to an array antenna with electronic scanning in the azimuth plane.
- focal line is used to designate the locus of points on which the reflector focuses. Two singular points are the positions of the sources s 1 and s 2 corresponding to the satellites in the extreme target orbital positions, and a plane contains these two points and the origin O of the focal axis of the reflector. Nevertheless, the focal line is not necessary rectilinear.
- FIGS. 6, 7 , and 8 show an antenna 2 having a reflector 10 of centered configuration mounted on a support 4 and provided with five transceiver sources s 1 , s 2 , s m , s 3 , and s 4 (FIG. 8) arranged on the focal line 6 .
- Each of these transceiver sources corresponds to a satellite on the geostationary orbit 8 .
- Conventional pointing of such an antenna comprises adjusting the azimuth angle, adjusting the elevation angle, and adjusting the roll angle.
- the azimuth angle is adjusted in conventional manner by turning about the axis A, the elevation angle is adjusted by turning about the axis B, while the roll angle is adjusted by turning about the axis C.
- the method of the invention includes an additional adjustment which consists in offsetting one of said transceiver sources on the focal line 6 of the antenna 2 through a distance d relative to the middle of said focal line 6 so as to aim at one of the extreme positions S 1 , S 2 .
- the distance d is calculated as a function of the angle ⁇ between firstly the line extending from the origin O on the focal axis of the reflector 10 to the target extreme position, and secondly the line extending from said origin O to the middle position S M of the geostationary orbit.
- This step can be preceded or followed by a step consisting in turning the reflector 10 through the angle ⁇ about an axis D perpendicular to the plane containing the focal line 6 and the origin O of the focal axis.
- the roll angle is then adjusted by turning the antenna 2 about its own axis pointing at the satellite situated at the extreme target position, so as to aim at the other extreme position and align the focal line 6 on the set of satellites situated between the positions S 1 and S 2 .
- the locus 20 of target orbital positions corresponding to the plane containing the sources s 1 , s 2 , s 3 , s 4 , and s m is not in alignment with the locus 22 containing the positions S 1 , S 2 , S 3 , S 4 , and S M .
- the sources s 3 and s 4 corresponding respectively to satellites situated in positions S 3 and S 4 are positioned on the focal line 6 at angles S 3 OS M and S 4 OS M in order to aim at said satellites.
- the sources are adjusted in the direction perpendicular to the plane containing the focal line 6 and the origin O of the focal axis of the reflector 10 so as to compensate for the non-perfect alignment of the satellites situated on orbital positions S 1 , S 2 , S 3 , S 4 , and S M .
- the method of the invention is implemented by a pointing device comprising a mechanism 30 for fixing the antenna 2 on said support 4 and also making it possible to turn the reflector 10 through an angle ⁇ about the axis D so as to steer the reflector transversely.
- said mechanism 30 comprises a U-shaped first part 40 co-operating with a second part 42 fixed via one end to the support 4 while its other end is mounted to move between the side limbs of said U-shaped first part 40 so as to enable the elevation angle of the reflector 10 to be adjusted.
- said first part 40 also co-operates with a third part 44 having a face 45 perpendicular to the focal axis of the reflector 10 .
- This face 45 has slots 46 in which studs 47 secured to the U-shaped part 40 slide so as to enable the roll angle of the antenna 2 to be adjusted.
- Said surface 45 also has top and bottom brackets 50 and 51 each pierced by the axis D so as to make it possible to perform adjustment of the angle ⁇ .
- at least one of the said brackets 50 , 51 has a slot 52 in which an arm 54 , 55 slides for performing rotation about the axis D and for holding the transverse direction into which the reflector is steered.
- the invention also applies to an antenna 2 having a single source that is motor-driven along the focal line 6 or a single source having a steerable radiation pattern.
- the method is applied to pointing an array antenna with azimuth scanning which is fixed on a support 4 and has a plurality of radiating elements suitable for aiming at a plurality of satellites situated between two extreme positions S 1 and S 2 on a geostationary orbit 8 .
- the device for implementing the method has a mechanism 30 for fixing the antenna 2 on said support 4 so as to make it possible additionally to turn the array antenna 10 through an angle ⁇ about an axis D perpendicular to the azimuth scanning plane of the array so as to steer the array transversely.
